SECTION 3

FUNCTIONS & FEATURES

3.1 FUNCTIONS

The MK-7 Buddy-Line hard-wire system utilizes the “four-wire” approach. It is a

closed loop comparable to a telephone system. A typical hard-wire system con-

sists of a surface intercom, a headset with a boom microphone, a ComRope (set

up for four wires, shielded or true spiral four), a diver microphone-earphone as-

sembly, a mask microphone, and some sort of diving mask with accommodations

for a microphone. The Interspiro Divator MKII “AGA” full-face mask (FFM) is

what most professionals prefer, according to our statistics. A hard-wire system

requires a physical connection (i.e., umbilical/ComRope) between the listener and

talker. The signal travels over the communication ComRope.

Most hard-wire intercoms can be configured for either two- or four-wire opera-

tions. Four-wire communications is defined as a duplex communication route.

Two wires provide the uplink signal path, and two additional wires provide the

downlink path. Thus everyone can be online simultaneously (similarly to a tele-

phone conference call). Since you never cut off the diver while talking, as is the

case with a two-wire system, the four-wire system is the safer of the two configu-

rations. Due to the increased efficiency achieved with a four-wire system (duplex)

and its simplicity of use, the MK-7 is designed for four-wire operation only.

The standard MK-7 configuration functions as follows: After the system is pow-

ered up and all connections are properly made, the tender’s speech is picked up by

the boom microphone located on the headset. The voice is amplified by the upper

electronics module and routed through the ComRope. Connected to the ComRope

at the diver’s end is the earphone-microphone assembly (typically an EMA-2 for

the Interspiro FFM). The tender’s speech is reproduced by the earphone part of

the EM cable. When the diver speaks, his voice is picked up by the mask micro-

phone located inside the mask being used. The voice is routed through the

ComRope, received by the upper electronic module, amplified, and then routed to

the tender’s headset. If a second diver is on-line, he will hear and talk as well in

the same manner. The volume of the tender and diver(s) is controlled by separate

volume controls on the outside of the upper electronics module.

- IMPORTANT SAFETY NOTES -

It is extremely important that the divers are dressed out in a manner that will

strain-relieve the ComRope. Commercial dive schools typically instruct students

to have the ComRope tethered to the diver’s harness or buoyancy compensator

with a quick release. If someone pulls on the ComRope and the diver loses

control of the ComRope, the pull is on the harness, not on the diver’s mask.

This setup prevents accidental removal of the diver’s mask.

Additionally, the divers should be dressed out to allow a quick disconnect from

the ComRope to allow for a situation where a diver must free himself from the

ComRope.

In the event divers and the surface tender lose voice communications, both

should have in place a back-up rope-pull system for communication. See Table

1 (p. 9) for the line-pull system recommended by Ocean Technology Systems.

Note: The ComRope can be set up for many types of diving masks and/or

earphone-microphone assemblies. If you are not sure what to order, consult

an OTS dealer or OTS directly for the configuration you require.

SECTION 4

OPERATION

Before operating the MK-7, make certain the batteries are fresh or fully charged

(see Section 5, Batteries & Charging). Ensure that all o-rings are in place and free

of debris or foreign matter. Verify that all connections are securely fastened. En-

sure the divers are dressed in such a manner that the umbilical/ComRope will not

snag. These procedures should be performed before each dive.

After you have completed the above steps, proceed as follows:

4.1 SETUP FOR THE TENDER

4.1.1 Place the headset with boom microphone on your head so the two ear-

phones are comfortably over your ears and the boom microphone is within

1/4 inch of your lips.

4.1.2 Connect the headset’s Amp connector to the upper electronics module’s

Amp connector (Fig. 1, #3 & 6).

4.1.3 Locate the Amp connector on the ComRope, and mate it to the Amp

connector located on the top of the electronics module (Fig. 1, #8 and

Fig. 2, #17). If there is a second diver, do the same for his connection.

4.1.4 Secure the MK-7 to your belt (or wherever is most comfortable) by using

the belt clip located on the back of the upper module.

Note: We recommend that the MK-7 main module have some sort of strain

relief at the tender’s end to keep the diver and/or ComRope from putting excess

strain on the connectors. Excess strain on the connectors would cause damage

to the MK-7 and/or loss of communications.

4.2 SETUP FOR THE DIVER(S)

4.2.1 Although the MK-7 Buddy-Line can be used with various full-face or

mouth masks, the mask most commonly chosen is the Interspiro Divator

MKII (“AGA”) full-face mask (FFM). The following are the setup pro-

cedures, if you have an AGA FFM. You should have already connected

the headset and ComRopes if you are following this manual (see Section

4.1, Setup for the Tender). We are also assuming you ordered and have

the ComRope set up for four-wire communications with a male Amp

connector on one end and a Hi-Use® connector on the other end.

4.2.2. The AGA FFM should already have the EMA-2 earphone-microphone

assembly installed. If not, install it per the installation instruction sheet

provided with the EMA-2.

4.2.3. Locate the Hi-Use® connector on the ComRope, and connect it to the Hi-

Use® connector on the EMA-2. Ensure the Hi-Use® connectors are free

FIGURE 3: Recommended Setup of the Diver ComRope

of debris and lightly lubricated with a high-grade silicone grease.

4.2.4 Strain-relieve the ComRope in two places on the diver’s end. The first

point should have some sort of “D-ring” heavily taped or tied about 4

feet from the Hi-Use® connector. This “D-ring” will be clipped onto the

diver’s harness or buoyancy compensator via a carabiner or some good-

quality quick-disconnector. This connection will help prevent the

ComRope from pulling on the diver’s full-face mask (Figure 3).

4.2.5 The diver should tie the ComRope, making a hand loop about 6 inches in

diameter about 10 feet from the Hi-Use® connector (Figure 3). The diver

will now be secured to his harness or buoyancy compensator and have a

hand-hold he should hold during the dive. The diver should have control

of the ComRope throughout the dive. He should feel what is going on,

giving topside directions when slack needs to be taken up or when more

rope needs to be paid out. If the diver lets go of the hand-hold, the

carabiner–D-ring combination will absorb the tension. In the event the

diver must break lose of the ComRope totally (i.e., in an emergency), the

diver should let go of the ComRope hand-hold and unsnap the device

holding the D-ring. The diver then should let topside know what is going

on before he detaches the Hi-Use® connectors. The diver then should

proceed directly to the surface and reestablish communications (see the

notes on page 8).

4.2.6. The tender should ensure the ComRope on his end is also strain-relieved

in some manner. This will prevent the diver or topside tender from pull-

ing on the connections made on the MK-7 Buddy-Line electronics mod-

ule.

Note: See p. 4 (in Section 3.2, Features)

for the item descriptions.

4.2.7 After all connections are made, you can test the system. Have the diver(s)

don the full-face mask. The tender will don the headset with boom mi-

crophone. The boom microphone should be positioned 1/4 inch from the

tender’s lips (keep the microphone as dry as possible).

The MK-7 Buddy-Line will power up the moment the headset and boom micro-

phone are connected. There is no on/off switch. As long as the headset is plugged

in, the MK-7 will be on and drawing power.

The tender controls all volumes. The volume control labeled “Tender” controls

the volume of the tender’s voice to both divers. The individual volume controls

labeled “Divers” control what the tender hears from each diver. The tender should

adjust all volumes a little at a time until everyone can hear well. Rotating any

control clockwise brings the volume up. Counterclockwise rotation brings the

volume down.

- NOTE -

1. If the diver is set up properly, the tender’s pulling on the ComRope should

pull on the diver’s hand loop first. If the diver is not holding the hand loop,

the strain should go to the belt “D-ring,” not the diver’s full-face mask or

diver’s earphone-microphone assembly.

Ensure the diver is dressed out such that no unnecessary loops that can

entangle him are present.

2. Excessive volume will cause distortion and hinder communications. Adjust

all volumes slowly until everyone hears clearly. A good rule to follow is

“Less volume is better than too much noise.”

- IMPORTANT SAFETY NOTES -

1. The diver should be dressed in such a manner that he can disconnect from

the ComRope and from the earphone-microphone assembly. If it becomes

necessary to make an emergency ascent, if the diver has to break voice

communications, and if line pulls cannot be established, the diver should

surface and establish communications as soon as possible.

2. We do not recommend you rely solely on MK-7 Buddy-Line voice commu-

nications. A back-up safeguard, such as line pulls, should be established

and practiced (Table 1).

- NO POWER! -

If you connect the headset with boom microphone and the MK-7 does not power

up, verify the batteries are fresh (new) or fully charged and that the battery

snap is connected.

SECTION 5

BATTERIES & CHARGING

With the MK-7 Buddy-Line is provided an SP-8 eight-cell AA battery holder lo-

cated in the lower housing (Fig. 1, #14, on p. 5). If you use alkaline instead of

rechargeable batteries, install the eight AA alkaline batteries as follows:

1. Locate the latches on the sides of the lower housing (Fig. 1, #15, on p. 5). Pull

up on the latches simultaneously.

2. Separate the upper and lower modules while being careful not to damage the

battery snaps, wires, or o-ring (Fig. 1, #12 & 13).

3. Remove the SP-8 eight-cell battery holder (Fig. 1, #14) and install eight fresh,

1.5-volt alkaline AA batteries per the diagram on the SP-8.

4. Carefully connect the wire harness connector (Fig. 1, #13) to the SP-8 battery

holder. Verify that both spring-type connectors mate firmly and that you have

not accidently bent the connectors.

5. Verify that the o-ring (Fig. 1, #12) is in place, lightly lubricated with a high-

grade silicone grease, and free of debris.

6. Insert the SP-8 battery holder into the lower housing. Carefully mate the upper

and lower housings together. Ensure that you do not pinch any wires and that

nothing is on the o-ring or mating surface.

7. Connect the latches from the lower housing to the upper strikes. Pull down the

latches simultaneously until fully down. This will spring-load the upper and

lower assemblies.

8. Look all around the MK-7 to verify the upper and lower assemblies appear

evenly attached with no high spots.

The RB-11 nickel-metal hydride (NiMH) rechargeable battery pack is avail-

able from Ocean Technology Systems or your local OTS dealer as an alternative to

alkaline batteries. The RB-11 is recharged outside the housing. To remove and

replace the RB-11 battery pack, follow the same procedure (above, #1–8) as for the

alkaline batteries but with the RB-11 instead of the SP-8 alkaline battery holder.

Recharging the batteries is a simple process. You will need an RC-16 (if in the

U.S.) or RC-16i (if outside the U.S.) battery charger, available from OTS or your

local OTS dealer. Connect the battery snaps of the charger and the RB-11 battery

pack. Plug the power input cord of the charger into an AC power outlet, 120 VAC

50 Hz with the RC-16 or 90–260 VAC 50/60 Hz with the RC-16i. Charge the RB-

11 for up to 14 hours, but no longer than that to avoid overheating the battery pack.

Note: The battery you receive may have upgraded specifications from what is stated

in this manual. Due to advancing battery technologies, we continually upgrade

our batteries and chargers. Contact OTS or your local OTS dealer for information

about the latest available battery and charger.

SECTION 6

TROUBLESHOOTING

Problem: Corrosion buildup on the connectors.

Possible Cause and Remedy

PC Failure to wash and lubricate connectors after use in salt water.

RRemove salt water residue or corrosion from the unit by wiping it with a

cloth saturated in warm freshwater (use detergent if necessary). Periodi-

cally check the connectors to ensure they are clean and lightly lubricated

with a high-grade silicone grease.

Problem: Poor or no communications.

Possible Cause and Remedy

PC Batteries are defective or dead.

R. Replace alkaline AA batteries with fresh ones. If using a rechargeable

battery pack, recharge it.

PC Connectors are not properly connected or are damaged.

RClean and check all connectors. Replace damaged ones.

PC Headset with boom microphone is not plugged in.

RConnect headset; unit should power up.

PC Diver(s) cannot hear topside, but topside can hear divers.

RCheck topside microphone and make sure the tender volume is turned on

and the microphone is about 1/4 inch from the tender’s lips.

PC Diver(s) can hear topside, but topside cannot hear the divers.

RCheck all connections. Check the diver’s microphone. Verify the diver’s

volume controls are turned up.

PC Tender and divers hear light music over the intercom.

RThis happens if you are using an unshielded umbilical and are close to a

transmitting station. The only way to solve this problem is to change to a

shielded ComRope.

Problem: A strong but distorted signal is received.

Possible Cause and Remedy

PC You are speaking too loudly into the microphone.

RSpeak with more moderate volume, slowly and distinctly.

PC Your volume controls are set at too high a level.

RSlowly adjust your volumes as to not overdrive the system.

SECTION 7

MAINTENANCE

The MK-7 Buddy-Line is virtually maintenance free and should give you great

service during the life of the unit. The following are recommended service tasks:

1) Try to keep the headset with boom microphone as dry as possible.

2) Do not store the ComRope in a sealed container without drying it first. It will

grow mold if not dry.

3) If the ComRope was used in salt water, soak it in freshwater for about five

minutes before drying.

4) If salt water gets onto the headset and/or MK-7, wipe it with a clean cloth and

freshwater. Warm water and a mild soap solution can be used. Wipe it off with

freshwater before drying.

5) Disconnect all connectors when storing.

6) Lightly lubricate the Hi-Use® connector with a high-grade silicone grease.

7) If the MK-7 is not going to be used for a long period of time, the batteries

should be removed.

- PLEASE NOTE -

Although the MK-7 Buddy-Line is a ruggedly constructed piece of your diving

gear, it should be treated like an electronic piece of equipment!

! ! ! CAUTION ! ! !

Use any standard safe entry into the water, but be aware of the additional equip-

ment you are wearing. Because the ComRope can snag on things, be aware of

obstacles in the area and avoid them. Make sure there is nothing in the water

the diver may hit upon entry.

SECTION 8

HELPFUL HINTS

A. All training should be conducted in a controlled environment such as a swim-

ming pool.

B. All personnel who intend to use this system should read and fully understand

this manual and equipment before they use it.

C. Divers should be dressed in such a manner that they can disconnect quickly

from the ComRope and/or earphone-microphone assembly.

D. The ComRope should be strain-relieved at both the diver’s and tender’s ends.

It is extremely important the divers have the ComRope strain-relieved to their

harness or buoyancy compensator and not to the full-face mask.

E. The topside tender is in control of the rope topside, ensuring that it is not

getting tangled and that it is not a safety hazard for those walking about.

F. The divers should be aware of their surroundings, making sure their ComRopes

do not become entangled.

G. When a diver must enter the water by jumping into the water, the following is

the recommended procedure: The diver should step up to the end of the pier

or edge from which he is about to jump. The ComRope will be connected to

the diver, who will be holding onto the hand loop he has made on the ComRope.

The tender should lower enough slack so as to just touch the water. The diver

looking out toward the horizon will start his giant step. As the diver steps off,

he turns to face the tender holding on to the ComRope. When he enters the

water, he should be looking at the tender.

- SAFETY NOTE -

If the diver plans to make a jump, it is extremely important the tender does

not forget to pull slack in the ComRope. The ComRope should barely touch

the water while still being attached to the diver. This gives the diver the amount

of rope necessary to hit the water with some slack. If there is no slack in the

rope, the diver could be seriously hurt by being hung or jarred.
